getdirentries - get directory entries in a filesystem-independent format
ssize_t getdirentries(int fd, char *restrict buf, size_t nbytes,
off_t *restrict basep);
Since glibc 2.19:
Glibc 2.19 and earlier:
_BSD_SOURCE || _SVID_SOURCE
Read directory entries from the directory specified by fd into
buf. At most nbytes are read. Reading starts at offset
*basep, and *basep is updated with the new position after
getdirentries() returns the number of bytes read or zero when at the end
of the directory. If an error occurs, -1 is returned, and errno is set
to indicate the error.
See the Linux library source code for details.

Not in POSIX.1. Present on the BSDs, and a few other systems. Use
